New paper alert 🚨 I am super happy about it, for many reasons! 👥 It was a great collaborative project with Calum @chgjohnston.bsky.social and J. Pablo Radicella, designed a long time ago (in the pre-AlphaFold era - can you imagine?) together with @polardlab.bsky.social and @raphguerois.bsky.social
Calum H. G. Johnston@chgjohnston.bsky.social · 11mo agoPleased to share our recent article in PNAS - a collaboration with @jessicaandreani.bsky.social & Pablo Radicella, with important roles played by many members of each team. A tripartite protein complex promotes DNA transport during natural transformation in Firmicutes www.pnas.org/doi/10.1073/...
There's some really big caveats to this. A thread.

Report also has interesting stories about state actors' AI use.
I honestly can’t believe there are still any AI skeptics out there. This tech is obviously revolutionary

Watching Spain and Portugal very closely, but please don't jump to conclusions. Lots of bizarre root causes in big power grids.
From one of the leading figures in industrial cyber security 👇 It’s too early to tell if what’s happened in Spain & Portugal was caused by a cyber attack or some sort of physical activity. There’s a history of jumping to the former conclusion before the latter is proved true. We don’t yet know

This is inaccurate. There is no known vulnerability with Signal's core tech. The memo was discussing phishing attempts, which Signal has worked to mitigate. And it was hastily reported. It's important not to spread misinfo that can confuse people into moving away from meaningfully private comms.

NEW: Security experts tell @wired.com that X was hit with 5 DDoS attacks on Monday, but that X likely went down because its infrastructure was left exposed. They also refuted Musk's claim that the attack originated in "the Ukraine area." @lhn.bsky.social reports: www.wired.com/story/x-ddos...

Elon Musk said a “massive cyberattack” disrupted X on Monday and pointed to “IP addresses originating in the Ukraine area” as the source of the attack. Security experts say that's not how it works.
